My (F22) FWB K (M36) had a side job of looking after people's boats in a town I lived in last summer. We were going to meet up with our other friend but had to check out one of his customer's boats which was a 60' yacht.

He went below deck while I checked out the pilothouse where the steering wheel was. I saw a Captain's hat and put it on and pretended to steer the boat. K came up and noticed me wearing it. "Bad girl!" He yelled. He grabbed me by the back of my shorts and moved back to a huge bench seat at the back of the pilothouse. He put me over his lap, pulled down my shorts and started spanking me with the hat still on. Standing up after spanking me, I grabbed at his bulge in his pants and started unbuckling his belt. I pulled his pants and boxers down and his hard cock flipped up in front of my face. I started stroking it and put my mouth on his tip and worked my way down. I kept stroking his bottom half while rotating my hand up and down while sucking on the top half. I lifted up his cock and started licking his balls while still stroking him. He pulled my hair back, stood up and placed my stomach on the bench with my ass sticking out. I felt his wet tip rubbing against my clit a few times before he went in. At first it was slow with him pushing against me when he was all the way in and then he sped up. He let go of my hair with his left hand and started rubbing my asshole with his right thumb. He started grinding against me until I gasped. "Did you cum?" He asked. "Mhmm" I replied nodding my head, making the Captain's hat fall off on to the bench. "Good girl." He said and started d going in and out of me harder until he came, I could feel his cock pulse and throb as he filled me with cum. I pulled my pants up and put the captains hat back by the helm. I probably looked like a duck, waddling to the Marina's bathroom as his cum was coming out of me. We made another stop at a park so he could take a vibrator to my clit to make me cum a few more times.
